Whether the appeal against the opposition decision was filed within the statutory deadline.
The appeal was filed too late because the 30-day period started on 2009-08-26 and expired on 2009-09-24.
The insured acknowledged receipt of the opposition decision on 2009-08-25. Under LPGA/LPA-VD, the appeal period begins the next day and runs for 30 days. Filing on 2009-09-25 was therefore untimely.
